The city's underwater rugby team is one of a number of local sporting groups lobbying to keep Civic Pool — which is slated to close — as its training facility.

Public submissions for the new aquatic centre in Commonwealth Park closed last month, and it's not yet known if the facility will have a deep pool to accommodate diving and water sports like underwater rugby.
